Critics argue that the technique may lead to designs that can't be properly evaluated since no human understands which trade-offs were made and therefore where failure is likely.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.newscientisttech.com/channel/tech/mg19526146.000-evolutionary-algorithms-now-surpass-human-designers.html"><P>Nonetheless, EAs face challenges. A common objection is that some electronic circuits and antennas work fine, but the mathematics behind them is intractable. And if you don't know how an evolved design works, how can you know when it might fail? But Koza calls that objection "self-serving and bogus". "Like any design you can test the hell of the one solution you settle on," he says.</P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/DC53C478-B068-497C-BE5A-589318B37519/blog/" title="blog or email this clip"><img src="http://content7.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
